I am using Office 365 with ADFS authentication.
When I go to portal.office.com, and the following is true, I get a This page can’t be displayed error just as the browser tries to authenticate against my ADFS server:
Using IE or Edge in Windows 10 (IE version: 11.103.10586.0)
Computer joined to my domain
On the WAN whether or not I'm connected to the VPN
It will work if:
I'm on my corporate LAN
There is no problem with Windows 8 in the above setup (IE 11.0.9600.12205)
If I use Firefox (probably chrome too, haven't bothered to test)
Other notes:
I can properly resolve the external address of my adfs server (otherwise Firefox wouldn't work)
If i replace the server address (adfs.domain.com) with the WAN IP, it will authenticate
My ADFS server along with *.microsoftonline.com and *.office.com is in my Local intranet zone.
Enabling or disabling "Display intranet sites in Compatibility View" does not resolve the issue
From what I can tell, IE cannot resolve the address of my adfs server or refuses to talk to it. I don't know how a browser would not be able to resolve an address because I don't believe it's the job of the browser to do name resolution/interpretation at any
level.
This affects all Windows 10 clients.
Before asking me if I have checked TLS settings, etc in IE please remember: I am able to connect to my adfs server if I use the IP address in IE.
Before asking if my DNS settings are setup properly: Firefox works fine without me entering the IP.
I'm stuck and have no idea what to try next.
